Copper (Cu) Powder

Copper is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a component of various metal alloys such as Sterling silver used in jewelry, cupronickel used to make hardware and marine coins and is constantly used in large gauges and thermocouples. For temperature measurement.

Copper is one of the few metals that can occur naturally in a metal that can be used directly (native metals). This led to very early human use in different regions, from c. 8000 BC Thousands of years later, it was the first fusion of sulfide, c metal ore. 5000 a. C., the first metal to be molded into a mold, c. 4000 BC and the first metal to be bound with another metal for purpose, tin, to create bronze, c. 3500 a. C. [4]

In Roman times, copper was extracted mainly in Cyprus, the origin of the name of the metal, of aes сyprium (metal of Cyprus), later it was corrupted to cup rum (Latin), from which derived the words, coper (Old English) and copper, used for the first time around 1530. [5]

The commonly found compounds are copper (II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been used in a general and historical way as pigments.

The copper used in buildings in general coverage is oxidized to form a green Verdi (or patina). Copper is sometimes used in decorative art, both in its elemental metal form and in compounds like pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.

Copper is essential for all living organisms as a trace of food minerals because it is a key component of the cytochrome c oxidase complex of respiratory enzymes. In mollusks and crustaceans, copper is a component of hemocyanins, a blood pigment, replaced by hemoglobin complexed with iron in fish and other vertebrates. Copper is found mainly in the liver, muscles, and bones in humans. [6] The adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight. [7]
